COLLEGE STATION, Texas — Former spy and current A&M professor Jim Olson paid a visit to the Brazos Valley Tuesday evening for an Issues Forum on his new book, "To Catch a Spy: The Art of Counterintelligence."

Olson made some remarks at the Thomas R. Frymire Auditorium and signed a few copies of his book.

Those that know the former counterintelligence operative say even after his career in the government, his mission lives on in the pages of his book.

"He's written this book to let people be aware that there are agents out there working against the U.S. Some of those are people who we think are trustworthy. We should be aware and maybe do a better job of catching the spies here that are sent by foreign countries and also those who are our own citizens who turn against us," said Warren Finch, Director of the Bush Library and Museum.

Tuesday's forum was part of an exhibit at the Bush Library called, "Spies, Traitors, Saboteurs: Fear and Freedom in America."

The exhibit gives a perspective into terror on United States soil, uncovering stories of domestic terrorists and foreign agents, militant radicals and saboteurs from the past 200 years.
